There are multiple devices, infact. Fans probably dont count as "devices", but those can be attached to motherboards. Then there's the GPU (Graphics Processing Unit a.k.a the Graphics Card) and the CPU (Central Processing Unit a.k.a the Processor). More can be attached but you can look those up on Google.
assuming the older mother board has similar sockets and slots for your current devices parts (and your motherboard supports those devices) you should have no problem downgrading
All the devices in your computer go through your motherboard. Excluding things such as fans and lights, which apon occasion do.
A motherboard that is mounted to tilt 90 degrees within a computer box is known as an ATX motherboard. The ATX motherboard was created by Intel in the 90's.
the motherboard? :S
The Motherboard functions as the main circuit board that connects and communicates to all the devices and components attached in the computer. The motherboard facilitates the communication of devices with each other.
The device installed under the bays of a motherboard is typically a storage drive, such as a hard disk drive (HDD) or a solid-state drive (SSD). These drives are mounted in drive bays to provide data storage for the computer. Additionally, there may be optical drives or other expansion devices depending on the motherboard's design and intended use.
motherboard is a most important part of system.Motherboard also now as main board or main CKT board or plaenboard all the component of system intrigrated are attached vaya motherboard.
The Processor (CPU)
It depends on the motherboard, and built-in devices. You might have to change the sound card, or the display adapter
it is used to connect expansion cards to the Motherboard
the clock on a motherboard ensures that all the devices run in sync
To manage simple devices (system BIOS)To start the computer (startup BIOS)To change settings on the motherboard (CMOS setup).
